One representative example is the Piezo 1 and Piezo 2 ion channels that manipulate mechanotransduction of cells by using conformational changes under mechanical stimuli to control ion permeability and selectivity4. Therefore, introducing the piezoelectric effect in biological systems has been considered as ...
The spontaneous polarization constant for MgO determined from a comparison with the experiment is about0.070C∕m2, which is larger than the value(0.050C∕m2)for ZnO. The negligible internal field effect observed in the case ofZnO∕MgZnOQW structures with relatively low Mg composition(x<0.2)and ...
Effect of piezoelectric transducer nonlinearity on phase shift interferometry If the nonlinearity of the motion of a piezoelectric transducer (PZT) can be described as a quadratic function, the integrated intensity of one frame in ph... C Ai,JC Wyant - 《Applied Optics》 被引量: 208发表: 1987...
Effect of Different Crestal Sinus Lift Techniques for Implant Placement in the Posterior Maxilla of Deficient Height: A Randomized Clinical Trial patients were treated using a Densah drill crestal sinus lift, Group 2: patients were treated using a piezoelectric crestal sinus lift and Group 3: pat...
PURPOSE:To provide a wide range flow rate adjustability for a piezo pump using a piezo actuator of vertical effect type by furnishing a supporting member to support a diaphragm body at the tip of a lever constituting an enlarging mechanism, and by fixing this supporting member to a fixation ...
area between the adhesive layer 15 and the piezoelectric ceramic body 11 is spread by the irregularities, adhesion between the piezoelectric ceramic body 11 and the adhesive layer 15 is increased effectively, thus preventing the peeling of the adhesive layer 15 at the time of usage with effect. ...
crystallographic consideration. This means that any crystal should exhibit piezoelectricity as long as it belongs to one of the 20 point groups lacking inversion symmetry. However, the effect was so weak in most known crystals that not many practical applications utilizing the piezoelectricity had been...
According to crystal symmetry, non-centrosymmetric materials in their various structures have symmetry-dependent piezoelectric responses. However, centrosymmetric crystals can exhibit a piezoelectric effect on breaking the inversion symmetry by adsorption of heteroatoms, introducing specific in-plane defects, ...
When applying a driving AC voltage signal to the electrodes, the AlN will start expanding and contracting in the lateral dimension due to the inverse piezoelectric effect. Since the membrane is clamped and suspended on top of a cavity, this will act as a boundary condition that will force the...
Lead free piezoelectric in the ternary system of 0.9BaTiO3-(0.1-x)CaTiO3-xBaSnO3 [BCT-xBS], where x = 0.00–0.075, was fabricated via a conventional solid state reaction. The effect of substituting BCT with BS on the crystal structure as well as dielectric, ferroelectric and strain behavio...
